I've had 12 on my laptop for a while but I don't use my work laptop often. I'm upgrading from 10 to 12. First dip into 64bit on my home PC. I've got 4GB of RAM now so its worth doing. I was using a PAE kernel before.

There are a couple of issues with 64bit but we'll see how it goes. Anyone know how 64bit Wine performs? Do 32 bit apps work as normal?
